ASSEMBLY
1. Remove the unit from the crate and open
packing cartons. Check for any damage that
may have occurred during shipment.
Advise factory immediately if you see any
damage.
2. Unpack spray gun support tube, spray gun
mounting bracket and spray shields.
3. Slide one spray shield onto gun support
tube from each end. (Longer part faces
upright). Snug star knobs. (Pic 1)
4. Slide tube with shields into receiving tube
on front of machine and snug star knobs.
(Pic 1)
5. Slide the spray gun mounting bracket onto
the upright and hand tighten star knob. (Pic
1)
6. Place the spray gun (without the hose
attached) in the holder and secure with the
clamp. (Pic 1)
7. Check placement of spray gun in gun
holder. Spray gun should be far enough
forward so that there is room between the
trigger and lifting bar attached to the plate
(1/8”-3/16”). This will allow the gun to shut
off completely when the trigger is released.
(Pic 1)
8. There should also be enough room to push
the trigger lock sideways. If the trigger lock
will not push, release the gun clamp and
slide gun backward until you can push the
trigger lock. Re-clamp gun. NOTE to release
trigger lock: Push the trigger lock in on the
right side (outside) of the gun. (Pic 1)
9. Attach one end of the spray hose to the
pump outlet with a ¾” wrench and the
other end to the spray gun. You will need
two wrenches (3/4” and 9/16” or two
adjustable wrenches) to secure the hose on
the spray gun as it has a swivel fitting.
Make both connections tight. (Pic 2)
10. Always check the oil level in the engine
before starting (SAE 10W30).
11. Make sure that the static chain is
contacting the ground (Attached to the
bottom side of the frame).
12. If unit was shipped with suction hose
removed at the pump. (Garden hose type
fitting). Depress Inlet Valve Stem to ensure
it moves freely. Attach suction hose. Hose
fitting may be hand tightened. You may
also need to perform this operation any
time the pump does not want to prime. (Pic

OPERATION
We recommend practicing with water to learn the controls and machine operation. Then if you are going to use an
oil-based paint, you will have to flush out the water with paint thinner (mineral spirits) prior to using the oil-based
paint.
1. Turn spray control (black knob) to the Prime/ re-
circulating position (arrows in a circle) in line with
the arrow on the side of pump housing.
2. Move Pump engaging lever to the “ON” position.
3. The Pressure Control Knob (Gold, knurled knob)
should be turned all the way in (Turn clockwise to
where it just stops. Do not over tighten)
4. You should see liquid start to flow back to the pail
in the return hose. Let his run until there are no air
bubbles in the return hose. If bubbles do not stop,
check tightness of suction hose fitting at pump. See
Notes below)
5. Turn Spray Control knob to spray position. (Spray
gun symbol in line with arrow on side of pump
housing)
6. Activate trigger and paint or water will spray from
the gun.
7. Adjust pressure by turning pressure control knob
counter clockwise until spray pattern decreases,
then increase pressure by turning clockwise just to
where you get a good even spray pattern.
8. Adjust spray gun height for proper line width.
9. To move forward, push the operating lever forward
until it locks. Speed may be controlled through the
engine throttle. To stop, pull the operating lever
backward.
10. When finished spraying or if machine will be left
unattended for any amount of time, turn Spray
Control Knob to Re-circulating Position, turn off
engine and pull spray trigger to release pressure
from the system
OPERATIONAL NOTE!
NOTE: If pump does not prime, turn off pump by moving the pump
engaging lever to the OFF position, then back out the pressure control
knob several turns (counter clockwise) until loose. Move the pump
engaging lever to the ON position, leave spray control knob in prime/re-
circulating position and let pump run for ONE MINUTE. Then turn the
pressure control knob back in until it stops. Push outlet button 3 times.
Pump should now prime.
NOTE: If the pump primes and air bubbles continue to appear in the
hose after one minute, the suction hose fitting may not be tight enough or
the rubber washer may be worn. Turn off machine, turn spray valve to
prime position and depress spray trigger to open gun and release pressure.
Remove garden hose fitting at the inlet side of the pump, depress inlet
valve stem to make sure it is free, inspect washer to make sure it is seated
and in good condition. Re-attach garden hose fitting making sure that it is
tight. You may have to snug it with pliers if you continue to get air bubbles.
Start engine and repeat first steps for operation.

TROUBLESHOOTING GUIDE
PROBLEM
REMEDY
Engine will not start
Check that the fuel shutoff and ignition switch are in the on position, choke
lever is in Choke position and throttle lever is in run position. Fuel tank has
adequate new fuel. Call factory for assistance.
Engine starts, but runs rough
Check that the choke is turned off.
Choke off but still runs rough
Check for proper fuel. Check spark plug for fouling. Clean or replace. Check
air filter.
Drive lever engaged, but
machine will not move
Drive rollers not contacting tire or contacting too lightly. Check tire pressure.
Adjust rod until rollers contact wheels firmly. Call factory for assistance.
Rollers contacting tire, but are
slipping
Tire pressure okay & rod adjusted, replace drive rollers.
Pump will not prime
(No fluid returning to pail)
Check that spray control knob is in Prime position (Circular arrows aligned
with arrow on housing). Push brass outlet valve button 3 times.
Outlet Valve Button pushed, but
will still not prime
Turn off pump, turn pressure control knob out (counter-clockwise) several
turns until loosens. Turn on pump and run for 60 seconds. Turn pressure
control knob all the way in. Pump should now prime. Call factory for
assistance.
Fluid is returning to pail in
bypass hose, but air bubbles are
still present in hose after 60
seconds
Check inlet hose fitting for tightness and worn or missing rubber washer.
Check suction hose for nicks or cuts. Call factory for assistance.
Pump primes, but gun does not
spray
Check spray control knob is in spray position. Check pressure control knob is
turned to high pressure (clockwise), until it stops. Do Not Force. Check
